Principle of pearlescent pigment

The excellent chemical and high temperature resistance of pearlescent pigments offers its wide application in coatings, inks, plastics and many other fields. They provide a new color system and color quality for these products. Pearlescent pigments have low levels of heavy metals and meet relevant safety technical standards, making them suitable for food packaging and children's toys. Both acid and alkali do not erode the pearlescent pigment at room temperature. Pearlescent pigments can not burn, do not self-ignite, do not conduct electricity, and can withstand high temperatures of 600~800 °C. Pearlescent pigments can also be used in reactive coatings for radiation curing systems (electron beam curing, photocuring). The special surface chemical structure of pearlescent pigments makes them excellent in hydrophilicity, so it can be applied to water-based coatings, but it has poor lipophilicity. Therefore, when used in organic systems, there is a problem of poor dispersibility, and surface treatment of pearlescent pigments is required. It also makes it well suited for use in organic systems.
